/* ============================================================================
   sheet.css — shared composite-sheet stylesheet for sales-call-prep assets.
   Every asset family's sheets/<family>*.html links this file.

   ⚠️ HEIGHT GUARD: TOTAL SHEET HEIGHT ≤4800px.
   Taller captures import EMPTY into Figma (proven 2026-07-13).
   If a family's slots exceed 4800px, split into <family>-a.html / <family>-b.html.

   One sheet = one Figma capture = intra-sheet layout guaranteed:
   .sheet-grid children keep FIXED relative positions, so everything on a
   sheet arrives in Figma exactly where it sits here. Never rely on
   cross-sheet positioning — that is the placement plan's job.
